One thing to be considerate of:
The tune will take a little while to adapt. You wont notice the full benefit or change right away. It may take a few hours of driving, or a couple of days to fully "settle" in.

I went from stock to stage 2, and while it was noticeable as soon as I left the shop, it wasn't immediately as drastic as I was anticipating. It wasn't until a day or two later that the change took full effect.

Got it back this evening, I must say I'm not unhappy. It's definitely different from Stage I. I actually thought it would be more engine sound than quickness. Throttle response is better. The car seems just faster. Tomorrow the S5 rear resonator goes on (left side only) Will report back.

Did you go all in for stage 2 with your HFC and FMIC? Can you upgrade to stage 2 and stay stock with those parts? I know you're not maximizing the tune. Intercooler isn't an issue for me, but I don't think I want to deal with spacers/potential CELs

What you'll notice is how long you waited to go Stage 2 and then kick yourself from it.
I always tell everyone to go straight to stage 2. You're going to love it.

Bingo. I didn't screw around. I went from Stock to Stage 2 and the difference blew me away. I later added the GFB DV+ to smooth things out. I'm thinking I need to do an intake and maybe a muffler delete as well. Enjoy!

With more boost, the stock DV has the potential to fail over time causing boost leaks. The DV+ does a better job of managing the pressure in the intercooler. By keeping more pressure in the intercooler, the turbo doesn't have to spool back up as much between shifts and the throttle response becomes better. That is a gross over simplification. It's money well spent.

DV + has caused more issues than benefits since it came out. The same thing with the Forge DV which gets stuck open. The OE DV will easily handle stage 2+ power. On the B7's the old diaphragm design would rip but the updated piston style revision D has yet to fail. B8 uses the same revision D.

Very true about adaptation. Low end power gains were almost immediate but it took about 2 days of driving around until the the top end started pulling like never before. Crazy how “stage 2” wakes up the car. I shit you all not, my buddies m sport 335xi with fob and mhd stg2 was neck and neck with my a4 (his diffuser was inching on me). Even when he was stock I’d pull on him all the time. Can’t wait to save up for k04

The HFC is a required piece for Stage 2.

The IC is not, but I already had it installed prior to the tune anyway.

My big surprise was when I filled up with E85 for first time after HFC install. Its almost like going up another stage. The difference between 93 and E85 was like stock to Stage 2.
IF you got the ALUM manifold go fill it up and report back.

Were you guys racing backwards or does he have no clue how to drive? 335 stock is 320hp/332 ft-lb torque with the E92 chassis. You're talking S4 numbers which means a stock A4 can pull on a stock S4? I'm just trying to understand how this makes any sense.

Nah man, stock 335’s make around the same power as we do on stage 2 to the crank. Not sure what kinda special sauce my tuner put in there but the thing moves.
